SUSE CVE-2026-33413
etcd is a distributed key-value store for the data of a distributed system. Prior to versions 3.4.42, 3.5.28, and 3.6.9, unauthorized users may bypass authentication or authorization checks and call certain etcd functions in clusters that expose the gRPC API to untrusted or partially trusted...
CVE-2026-33413
A flaw was found in etcd, a distributed key-value store. Unauthorized users can bypass authentication or authorization checks when the gRPC API is exposed to untrusted clients. This allows them to access sensitive cluster topology information, disrupt operations through alarms, interfere with lea...

CVE-2026-4747 Remote code execution via RPCSEC_GSS packet validation
Each RPCSECGSS data packet is validated by a routine which checks a signature in the packet. This routine copies a portion of the packet into a stack buffer, but fails to ensure that the buffer is sufficiently large, and a malicious client can trigger a stack overflow. Notably, this does not...
CVE-2026-4747
CVE-2026-4747 is a FreeBSD vulnerability in the RPCSEC_GSS implementation (kgssapi.ko) where svc_rpc_gss_validate() copies attacker-controlled data into a 128-byte stack buffer without enforcing size, enabling a 304-byte overflow when credential bodies up to 400 bytes are supplied. This can lead ...

Improper Check for Unusual or Exceptional Conditions
Overview @grackle-ai/server is a Grackle server orchestrator — spawns and wires core gRPC, web-server HTTP, MCP, and PowerLine Affected versions of this package are vulnerable to Improper Check for Unusual or Exceptional Conditions in the JSON.parse process within the gRPC service adapter...
@grackle-ai/server JSON.parse lacks try-catch logic in its gRPC Service AdapterConfig Handling
Impact JSON.parseenv.adapterConfig is called without error handling in three locations within the gRPC service. While the data originates from the server's own SQLite database and should always be valid JSON, database corruption, migration errors, or unexpected state could cause an unhandled...
FreeBSD -- Remote code execution via RPCSEC_GSS packet validation
Problem Description: Each RPCSECGSS data packet is validated by a routine which checks a signature in the packet. This routine copies a portion of the packet into a stack buffer, but fails to ensure that the buffer is sufficiently large, and a malicious client can trigger a stack overflow. Notabl...
The vulnerability of the rxrpc_propose_ACK() function in the net/rxrpc/ar-internal.h module, which supports RxRPC session sockets in Linux kernel, allows a attacker to cause a service failure.
The vulnerability of the rxrpcproposeACK function in the net/rxrpc/ar-internal.h module, which supports RxRPC session sockets in Linux kernel, is related to a race condition. Exploiting this vulnerability could allow an attacker to cause a service failure...
The vulnerability of the rpc_sysfs_xprt_state_change() function in the net/sunrpc/sysfs.c module of the Linux operating system’s RPC protocol implementation allows a attacker to cause a service failure.
The vulnerability of the rpcsysfsxprtstatechange function in the net/sunrpc/sysfs.c module of the Linux operating system’s RPC protocol implementation is related to errors during the update of the reference counter. Exploiting this vulnerability could allow an attacker to cause a service failure...
UBUNTU-CVE-2026-33186
gRPC-Go is the Go language implementation of gRPC. Versions prior to 1.79.3 have an authorization bypass resulting from improper input validation of the HTTP/2 :path pseudo-header. The gRPC-Go server was too lenient in its routing logic, accepting requests where the :path omitted the mandatory...
